[R-390] Gender of connectors

[eldim at att.net]

Hello Fellow R-390A Entusiasts,
Here is my last 'TWO CENTS" worth as a contribution to this wonder list. The FXR Type MB RF "T" Adapter that FRS has pictured is incorrectly identified. NO BIGGY, as this was one of the most easy connectors to misidentify when one was always used to using "BNC" connectors.  
The R-390A Receivers Chassis Mounted MB Connectors are ONLY "male" or pin gender. Just to show how confusing this can be I did a print our and study comparison of the Federal Logistics "FEDLOG" Data for the FXR # 47325" and the Replacement NSN.  Who ever supplied the information  description information for the NSN assigned this Connector's Part Number, MADE THE SAME ERROR; which is consistent with the FRS description.  It might be noted that this NSN has been discontinued and been replaced with another NSN which has about 10 different part numbers vs  4 part numbers for the earlier NSN.  However, the Description under the New NSN CORRECTLY identifies the gender arrangement as male-female-male, or more technically correct: PIN Bayonet Shell, SOCKET Bayonet Latch, PIN Bayonet Shell.
Hope this finds you all in good health and enjoying the lovely weather of summer.
